Product details
Overview
TC7SZ125FU,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel 3-state bus buffer IC designed for level-shifting and signal isolation in low-voltage digital systems. It supports 1.65–5.5 V supply operation, delivers ±24 mA output drive at 3.0 V, and achieves 2.6 ns typical propagation delay at 5.0 V with 50 pF load-enabling high-speed data routing in automotive body control modules.
For engineers reviewing the TC7SZ125FU,LJ(CT datasheet, TC7SZ125FU,LJ(CT pinout, TC7SZ125FU,LJ(CT application, or TC7SZ125FU,LJ(CT equivalent, this device offers AEC-Q100 qualified performance, 5.5 V-tolerant inputs, and power-down protection-critical for robust interface design in mixed-voltage automotive ECUs and industrial I/O expanders.
Technical Context
This CMOS logic buffer implements a non-inverting 3-state output controlled by an active-low enable (G) input. Its architecture supports bidirectional bus isolation with high-impedance output when disabled, eliminating contention during shared-bus arbitration.
It features 5.5 V-tolerant inputs independent of VCC, enabling seamless interfacing between 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains without external level shifters. The device maintains guaranteed switching thresholds across its full operating temperature range of −40 °C to +125 °C for J(CT-suffixed variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same SOT-25 package and 3-state function; lower max VCC (3.6 V), no 5.5 V input tolerance. | Suitable only for pure 3.3 V systems; requires external clamping for 5 V signal sources. | Select when cost sensitivity outweighs mixed-voltage flexibility and AEC-Q100 compliance is not required. |
| 74LVC1G125GW,125 | NXP variant with identical pinout and 1.65–5.5 V range; lacks AEC-Q100 qualification and specified −40 to +125 °C operation. | Approved for commercial/industrial use only; not validated for automotive under-hood thermal cycling. | Choose for non-automotive embedded systems where extended temperature range is unnecessary. |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the TC7SZ125FU,LJ(CT uniquely combines AEC-Q100 qualification, 5.5 V input tolerance, and guaranteed −40 to +125 °C operation in the same compact SOT-25 footprint-making it the sole drop-in solution for safety-critical automotive signal routing where voltage interoperability and thermal resilience are mandatory.

FAQ
What is the maximum operating temperature range for TC7SZ125FU,LJ(CT?
The TC7SZ125FU,LJ(CT is rated for −40 °C to +125 °C operation, confirmed by AEC-Q100 Rev. H qualification testing. This range applies specifically to parts with the J(CT suffix, as noted in Toshiba's datasheet revision 3.0.A, making TC7SZ125FU,LJ(CT suitable for under-hood automotive applications where ambient temperatures exceed 105 °C.
Does TC7SZ125FU,LJ(CT support 5 V input signals when powered from 1.8 V?
Yes, TC7SZ125FU,LJ(CT features 5.5 V-tolerant inputs, allowing it to accept 0–5.5 V logic signals regardless of VCC voltage (1.65–5.5 V). This capability is explicitly verified in the Absolute Maximum Ratings table and Operating Ranges section of the official Toshiba datasheet, enabling direct interfacing with legacy 5 V peripherals without external level-shifting components.
Is TC7SZ125FU,LJ(CT pin-compatible with SN74LVC1G125DBVR?
TC7SZ125FU,LJ(CT and SN74LVC1G125DBVR share identical SOT-25 (5-pin) pinout and terminal functions (A, G, GND, Y, VCC), but differ in key specifications: TC7SZ125FU,LJ(CT supports 5.5 V inputs and −40 to +125 °C operation, while SN74LVC1G125DBVR is limited to 3.6 V VCC and commercial temperature range-so mechanical replacement is possible, but functional equivalence requires validation against system voltage and thermal requirements.
What is the typical propagation delay of TC7SZ125FU,LJ(CT at 3.3 V supply?
At VCC = 3.3 V and CL = 50 pF, the typical propagation delay (tPLH/tPHL) of TC7SZ125FU,LJ(CT is 2.5 ns, as specified in Section 9.4 AC Characteristics of the Toshiba datasheet. This value is measured under standard test conditions (tr/tf = 3 ns) and reflects the device's ultra-fast switching performance in common 3.3 V industrial and automotive logic interfaces.
Does TC7SZ125FU,LJ(CT include power-down protection on its output?
Yes, TC7SZ125FU,LJ(CT provides 5.5 V power-down protection on its 3-state output (pin 4/Y), meaning the output remains high-impedance and cannot source or sink current when VCC = 0 V-even if 5.5 V is applied to the output pin. This feature is documented in the "Features" section and Absolute Maximum Ratings table of the official Toshiba datasheet, safeguarding downstream circuitry during partial power loss scenarios.
